...this is also a way of degrading insert/update/delete performance. There are no panacea to good performance, otherwise such options would be on by default.
An answer to your question could be very large. A few things that spring to mind:
Deploying your database in a cluster
Using more powerful database server(s)
Getting more bandwidth between your client and the database
Making sure statistics are well maintained
Sending extra instructions to whatever query engine your database uses (if this is supported)
Breaking large queries down into smaller queries and doing more work in the client
Use query hints (if your database supports this)
Increase the temporary space available in your database (if your database requires this)
Don't use functions
Don't use transactions
Avoid correlated subqueries if possible
and so on.
I agree. Here's the link:
